NiSi Square Nano IRND 100x100mm ND1000 10Stops

NiSi Square Nano IRND 100x100mm ND1000 – 10 Stops of Neutral Density with IR Protection

The NiSi Square Nano IRND 100x100mm ND1000 delivers 10 stops of neutral density to extend exposure time and expand creative possibilities. It uses high definition optical glass and an infrared protection coating to preserve natural, vibrant colours during long exposures.

Description

NiSi Nano Coated IR Neutral Density filters consist of high definition optical glass, not resin. They feature double-sided nano coating technology to reduce reflections and help retain image detail. As a result, you can shoot longer exposures while keeping tonal fidelity.

Neutral density filters reduce the amount of visible light entering the lens without affecting the image coloration. However, cameras become more vulnerable to infrared light when using strong ND filters at small apertures. NiSi addresses this by adding an infrared protection coating layer that helps eliminate infrared light reaching the sensor, thereby reducing unwanted red colour cast and restoring natural colour balance.

Who it’s for and use cases

This filter is specially designed for landscape photographers who need longer exposure times for creative effects such as smoothing water, motion blur in clouds, or reducing depth of field in bright conditions. Use it when you want controlled light reduction while maintaining image detail and true-to-life colour.

FAQ

Question: Will this filter change the colours in my images?
Answer: The NiSi Nano IRND is designed as a neutral density filter, so it does not affect visible light coloration. Additionally, the infrared protection coating helps prevent IR-induced red casts that can occur with strong NDs at small apertures, preserving more natural colours.

Question: What material is the filter made from and why does that matter?
Answer: The filter uses high definition optical glass (H-K9L), not resin. Optical glass maintains image detail and clarity, and when combined with double-sided nano coating it reduces reflections and retains sharpness.

Question: How does the nano coating benefit me in the field?
Answer: The double-sided nano coating lowers reflections and helps keep the glass clean. It also provides water and oil repellency, which makes it easier to maintain the filter during outdoor shoots and reduces the need for frequent cleaning.

Question: Which exposure scenarios benefit most from this 10-stop ND filter?
Answer: Use the 10-stop ND for long exposures in landscape photography—such as smoothing water, creating motion blur in clouds, or achieving slow-shutter effects in bright conditions—while maintaining accurate colours thanks to the IR protection.
